The Basics of Coffee Roasting

Coffee roasting is an art and a science, transforming green coffee beans into aromatic brown beans that are ground, brewed, and enjoyed by millions around the world. This process is not just a mere alteration but a complete metamorphosis of the beans’ chemical and physical properties, defining the unique taste profiles of the coffee we drink.

What is Coffee Roasting?

Coffee roasting is a meticulous process that turns the raw, green coffee beans into the flavorful, roasted varieties used in brewing. This process involves:

  • Chemical Changes: Roasting initiates a series of chemical reactions, most notably the Maillard reaction, akin to what happens when cooking a steak. This reaction develops the rich flavors and aromas characteristic of coffee.
  • Physical Transformations: The beans undergo significant physical changes. They lose moisture, expand in size, and change from green to various shades of brown. The loss of water content, about 16% in unroasted beans, is a critical aspect of this transformation.
  • Flavor Development: The roasting process profoundly affects the beans’ flavor. Unroasted beans contain high levels of acids, proteins, sugars, and caffeine but lack the complexity and richness of roasted beans.
  • Historical Context: The evolution of coffee roasting has been marked by innovations, from using simple pans in the Ottoman Empire and Greater Persia to modern, sophisticated commercial roasters developed in the 19th century. (2)

Coffee roasting is a transformative process that unlocks the rich flavors and aromas hidden within green coffee beans, making it a crucial step in the journey from bean to cup.
